AI agent finds 18-year-old remote code execution flaw in Nginx
Summary
Researchers, using an AI-powered platform, have discovered an 18-year-old heap buffer overflow vulnerability (CVE-2026-42945) in the Nginx web server. This flaw, present in versions 0.6.27 through 1.30.0, can lead to remote code execution under certain conditions, particularly on systems with Address Space Layout Randomization (ASLR) disabled.
IFF Assessment
This vulnerability allows for remote code execution, which is a critical threat to system security and data integrity.
Severity
The CVSS score of 9.2 indicates a critical severity, reflecting the potential for remote code execution and denial of service, making it highly exploitable.
Defender Context
This discovery highlights the ongoing risk of long-standing vulnerabilities in widely used open-source software. Defenders should prioritize patching Nginx instances and related F5 products, and ensure ASLR is enabled and effective as a mitigation against potential exploits.
